There are two of the “original” model, one with a dual extruder.
After months of use, my overall assessment is positive: they are good machines, fast and accurate, despite some minor defect.
For these printers I’ve used the Cura program to “compile” the 3D model and transform it into a set of G-code instructions to send to the printer.
The first problem that has occurred in Project “Math Exhibition” was the fact that some of the 3D models were provided in X3D format, that “Cura” is not currently able to import.
